Description: The new horizontal electrophoresis apparatus was designed with safety and convenience in mind. The injection-moulded UV transparent chamber is made from thick acrylic, making it durable and leak-proof while the lid fits securely in place and can easily be removed. All of electrophoresis units feature adjustable levelling feet, recessed electrical wires, and a safety stop that prevents the gel from running when the cover is not securely fitted. Each casting tray with embossed gel ruler has rubber end caps and multiple slots for easy and versatile comb placement. This unit requires 500mL of buffer and a power supply. This economical 2-part exercise provides an introduction to agarose gel electrophoresis. In the first part of the exercise, students identify unknown dye molecules by comparing their electrophoresis migration with the migration of known dyes. In the second part students identify dye molecules that bind to DNA and determine the mechanism. The exercise was designed for 8 groups of students and includes four colourful dye mixtures and DNA. Unit includes : (1)Injection moulded UV transparent base (1)Transparent cover (1)7x14cm Casting tray with embossed gel ruler & rubber end caps (1)8/10 Comb combo (2) Six tooth comb
